- The Schedule referred to in these Letters Patent and making part of the same.

To an whom it may conccrlt Be it known that'l, WILLIAM W. LYMAN, of Men, iden, in the countyIof New Haven and State of Con: f

necticut, have invented anew Improvement in Apparatus for Cooking Fruit; and I do hereby declare 'the;

following, when taken in connection with the accom-.

,panying' drawings and the letters of reference marked" thereon to be a full, clear, anthexact description of the; H same, andwlnch said drawings constitute part of this spec ficat on, and representcin-- Figureha vertical central section, and in Figure 2, a top view.

This invention relates toan improvement in apparatus for cooking fruit, or preparing it after it has been placed in cans" to beclosed for preservation.

. This process is usually and best, performed by steaming, and, while, it-is essential. that the fruit be cooked, it must not be o 'erdone heuce, it is desirable to time h the cooking, and-this I accomplish by my apparatus,

which is also applicable to other purposes; and con sistsin the arrangement of a cover withiua boiler so as to 'set down over the can placed therein.

true cover is formed with an edge, so as to set down into the water and form a packing, and provided with a safety valve for the escape of the steam, and also i with an alarm, so that the boiling-point will be denoted bedenoted.

A is a boiler, of any common or known construction, within which I arrange a perforated plate, B, upon by the steam sounding alarm, from which the time may 1 which several cans, O, are set, and the boiler filled with water to about the line a. a.

D is a cover or plate fitting closely into the boiler, and yet so as to beeasily raised orlowered therein, and provided with an edge projecting downward, so as to extend into the water, as denoted in fig. 1, inclosing 'the'cans ina chamber formed within the boilerby the plate 1).

lhesaid plate is provided with asafetywalve, f, and -with a whistle or other alarm, .0.

The fruit having been placed in the -caus, -t he cans areset-iuto the boiler and covered, then set over the fire, and left until the water 'bo'ils,the"t ime of boiling denoted by the escape steam sounding the alarm e.

, Thus, the time being noted-the fruit is then-left un til the water has boileda given length of time. i

This process is found to cook the fruit insthe-most successful manner; the constant presence of hot steam entirely around the cans, cutoff from the atmosphre,; insures the successful cooking. I i For other steaming purposes, the" plate B may be raised to any desirable point, and the cover D lifted and secured at the'upper edge of the boiler by the sliding bars E, or other sui-table'device for holding it in that elevated position. This forms a convenient steamer for bread, .eakes, &c.

1 claim as my invent1ou 4 v 1. The arrangement in a steaming-apparatus of the cover D with. its edge (I, constructed so as to extend into the water and form a packing, combined with an alarm, e, to sound the time of boiling,substantially as set forth. v 3

2. In combination wit-h the foregoing, the perforated plate B, as and for the purpose specified.

3. In combination with the foregoing, the supports E, substantially as described, to support the cover in an elevated position, substantially as and for the purpose set forth.

WILLIAM LYMAN.
